Iceman gets coldsnap from the start of the fight when he is awakened. If you know that coldsnap makes it so the opponent can’t evade while it is active and having that at the start of the fight is great. Wolvie can use sig stones till 99 and they will continually make him better with each one. Iceman on the other half only increases coldsnap damage with each sig.

If you have the sig stones, do Wolverine.
Otherwise, it would be better on the Iceman.
